Operation
1.
Basic operation
Figure 20 shows the block diagram of S-1135 Series.
The error amplifier compares the reference voltage (Vref) with Vfb, which is the output voltage resistance-divided by
feedback resistors Rs and Rf. It supplies the gate voltage necessary to maintain the constant output voltage which is
not influenced by the input voltage and temperature change, to the output transistor.

Output transistor
In the S-1135 Series, a low on-resistance P-channel MOS FET is used as the output transistor.
Be sure that VOUT does not exceed VIN + 0.3 V to prevent the voltage regulator from being damaged due to inverse
current flowing from the VOUT pin through a parasitic diode to the VIN pin.
